Cannot activate two wireguard connections in VPN Fusion

[b82m]

I am trying to setup to WG connections in Fusion based on Surfshark. Unfortunately only one wg connection works at a time.
If I look into the protocol, the only message I find is:
rc_service: httpd 2426:notify_rc restart_vpnc
Nothin else.
Any idea? I am already using two separate key, and subnets. Router: AX86U Pro
Here are my two configs:

[Interface]
Address = 10.14.0.2/16
PrivateKey = <My FIRST key>
DNS = 162.252.172.57, 149.154.159.92
[Peer]
PublicKey = <public key>
AllowedIPs = 0.0.0.0/0
Endpoint = de-fra.prod.surfshark.com:51820
